CLOSURE FOR ROLLS OF WIRE NETTING Filed July 16, 1963 INVENTORS MERRILL W. WRIGHT ROGER E BEDARD EDWARD F. DELAGE BY Mfz,

ATTORNEY United States Patent NETTING Woven wire fabrics such as poultry wire, wire netting and similar fabrics, are customarily produced in substantially endless strips and as produced the strips are wound in coils or courses to form rolls, the strips of fabric being cut across parallel to the axis of the roll in lengths providing the desired amounts to be shipped in each roll. This cutting makes sharp, raw ends of wire. In order to secure the roll for shipment, an operator grasps each cut end of the wire at the trailing end of the roll with a plier and with a twisting motion he forces the cut end into the fabric of the netting and slightly backwards in what might be described as a series of hooks to keep the material from unwinding and also to avoid the raw edges and cut .ends of the wire.

Accordingly it is the principal object of this invention to provide means for more quickly and easily securing the trailing end of the roll for shipping purposes and to obviate any damage which may be done by the trailing end without the necessity of having the operator individually grasp each cutting end and twist it under.

To this end this invention provides a closure member for the roll which may be a substantially fiat, elongated piece of cardboard, thin plastic or other self-sustaining but inexpensive material which can be placed over the trailing end of the roll, i.e., over the cut ends, together with staple-like means penetrating the closure member, extending into a course or two of the wound roll and then having the ends of the staple turned inwardly in order to grasp or engage the same, thus closing the roll and holding the cut trailing end thereof between the closure member and the roll itself. When it is desired tobe used it is a simple matter to separate the closure merely by grasping it and pulling it from the roll, exposing the cut end of the roll and leaving the poultry wire or netting ready for use.

The stapling can be done on conventional machines which are available and which are not further described herein. Other changes and combinations of parts may be made without departing from the scope of the invention and different sizes and kinds of staples and stapling machines may be utilized. The staples may be arranged longitudinally of the roll, i.e., parallel to the axis thereof or transverse thereto, and the legs of the staples may pene trate the roll to any depth which is found to adequately secure the closure member in the position described.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which:

FIG. 1 is a view in elevation illustrating a form of the invention;

FIG. 2 is a similar view showing a modification;

FIG. 3 is a section on line 3-3 of FIG. 2; and

FIG. 4 is an end View, looking in the direction of arrow 4 in FIG. 2.

In illustrating the invention, the disclosure is such as to 3,172,532 Patented Mar. 9, 1965 ice explain the invention without going particularly into the exact formation of the wire netting which is a common commercial material easily obtainable. This wire netting is woven and may be in the form of well known poultry wire, hardware cloth, or other similar materials. It is formed substantially continuously in an elongated strip which as it is formed, is customarily wound upon itself in coils or courses. When a requisite amount of the strip has been so wound, as for instance twenty-five feet, fifty feet, etc., it is cut off parallel to the axis of the roll, i.e., transversely across the machine on which it is formed, and this provides a trailing end which it is desired to be secured in position in order to prevent unwinding of the roll.

The reference numeral 10 indicates a roll of the woven fabric such as poultry netting or the like and the numeral 12 indicates the cut trailing end which is desired to be secured to the roll.

A strip of material 14 which may be of cardboard, or any other suitable inexpensive but substantially self-sustaining material such as plastic is provided in a length substantially the length of the roll so as to cover substantially the entire trailing end 12. When the roll is so cut, the operator merely applies the strip of material 14 to the edge 12 and staples it with conventional staples 16. These staples have legs 18 which extend through one or more courses or coils 20 of the roll 10 and well known machinery turns the ends in forming the feet 22 at least one course or coil of netting, closely holding strip 14 to the roll and covering the cut edges.

When it is desired to open the roll, it is very easy to manually strip off the strip 14 and the roll is ready for use.

In FIG. 4 it is seen that the strip 14 is turned in slightly at its edges as at 24 to conform to the contour of the roll, providing a tight complete package from the factory.

However it is not necessary to provide these inturned edges and as shown in FIGS. 2 and 3 the staples can be arranged longitudinally of the roll or transversely thereof as shown in FIG. 1, but in any event the construction is the same. The strips 14 can be flat or made on the arc of a curve or have their ends bent in slightly as shown, and the degree of penetration of the legs of the staples is merely sufficient to secure the closure member 14 to the roll.

Having thus described our invention and the advantages thereof, we do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what we claim is:

1. In a roll of wire net material wherein an elongated strip of the material is wound upon itself in a plurality of courses terminating in a trailing end at the outer surface of the roll, the combination with said roll of a closure therefor, said closure comprising a member having a length and width to overlie and protect substantially the length of the trailing end of the roll, and means holding the member in said end-overlying position and connecting the trailing end to the roll, said means comprising an element superimposed on and connected to the member, the element including portions thereof penetrating at least one course of the roll, said portions each having a terminal end extending at an angle thereto to engage under a portion of the wire of the penetrated course.

2. The combination of claim 1 wherein the element is a staple.

3. The combination of claim 1 wherein theelement is a staple and the portions penetrating the roll comprise legs on the staple.

4. In a roll of Wire net material wherein an elongated strip of the material is Wound upon itself in a plurality of courses terminating in a trailing end at the outer surface of the roll, the combination therewith of a closure for the roll, said closure comprising a generally flat member overlying and protecting substantially the length of the trailing end of the roll, and at least one generally U-shaped element the legs of which penetrate the member 5 element is a staple,
